Title: Method for registering article information in label printer
Inventor: NAKAMOTO AKIRA
IPC: G01G19/415
Filed: 1986-04-01
Abstract: PURPOSE:To perform renewed registering without performing the rearrangement of residual article information, by controlling an article explanatory sentence data writing area on the basis of 'explanatory document writing head address' and 'writing length' of rewriting prohibition with respect to erasing operation. CONSTITUTION:At the time of the first registering, by registering 'call number', 'unit price' and 'product name' at every article, 'writing head address' 'writing length', An and Ln, etc. are written in a non-explanatory sentence area E1 corresponding to 'call number' and 'unit price'. For example, when 'article 2' is erased, only 'call number' of 'article 2' of the non-explanatory sentence area E1 is rewritten to a specific erasion code by a control apparatus 2. When the novel registering of 'article 4' is performed, if there is an erased code, said code is registered with 'article 4' and, when there is no erased code, 'name of article 4' is written from the address A4 of an area F2 and 'call number', 'unit price', A4 and L4 are written from the address next to L3 of an unused area F1.
